Under Helm Dash Power Source

Unread post by SeaDawg »

So I am admittedly not very savvy when it comes to wiring...but can handle the basics if I have good instruction. My issue is that I need to connect power for my alternate Sonar / Chart Plotter. I have the appropriate gauge wiring (red (pos) and black (neg) run from the display unit to under my helm dash with plenty of extra wire if needed. I just need to figure out the place to tie into power and ground. Going directly to the batteries is really not a good option for me so hoping for a good location up and under the helm.

Any advice or photos would be greatly appreciated..

Jon's suggestion is where I'd look too, there should be spare slots available.

Just finished wiring mine. There should be 4 to 6 empty spots on the fuse block under the steering helm.
Just take the plastic cover off and you will see positive and negative terminals. Must put a medium size fuse ( make sure you put proper size of fuse in) in the positive side to get power to the electronics you install.

I also have a question on wiring and power sources. I have two possible sources, the fuse box, first picture and a switch panel with two unused switches, second picture. Should the fuse box and switch panel already be grounded or would I need to use a ground from any device I chose to add?

See the black cables entering on right side of your fuse box, that's the ground side, and one of those wires (probably the large one coming in from top) is connected to negative battery terminal. Switch panel is already connected to fuse box, note the red and black wires on all the switches. Should only need to add load wires to either of the two switches at lower right in your picture and maybe a fuse. If I had a schematic for newer OP I could say with certainty. ;)

I ran my planar to the fuse box. There was an empty slot but I had an in-line fuse in mine and the terminals were too big for that space anyway so I just connected to the main power & ground. Don’t know if that’s kosher but it seems to be working. When I actually get some electronics and run out of space I’ll probably add another fuse block or something similar.

Nate as long as you included a circuit protection device inline for the Planar you'll be fine. ;)

For me one of the biggest challenges when adding accessories that require 12V power is the sheer lack of space to work under the Helm dashboard. It is a tight space anyway, but with the Lowrance Autopilot, that requires hydraulic pump and hoses, NAC1 module, NMEA 2000 backbone etc shoehorned in there, just makes it dammed hard to access the fuse block that is installed there.

I know others have done similar things, but my solution was to add a second 6 position BlueSea fuse block under the dash on the passenger side. Make it so much easier.

It does get challenging, and adding an auxiliary fuse block can ease some wiring stress. Not much room left under the helm of our ProV...
